CARRIER FOR PNEUMATIC-DESPATCH TUBES.

Specification of Letters Patent. Patented J 11119 21 1910,

Application filed May 5, 1908, Serial No. 430,959. Renewed May 11, 1910. Serial No. 560,727.

To all whom it may concern:

Be it known that I, ALBERT W. PEARsALL, of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Car riers for Pneumatic-Despatch Tubes, of which the following is a specification.

My invention relates to improvements in carriers for pneumatic despatch tube apparatus and its object is to simplify the construction of the same by providing means for limiting the rotation of the shells or arrow, with parts broken away and showing the carrier open. Fig. 4 is a similar View to Fig. 3 showing the carrier closed.

Like letters of reference refer to like parts throughout the several views.

A represents the inner shell of an ordinary pneumatic carrier with the usual pe ripheral openin B and carrying secured at one end the bu er C by means of screws D and nut' E. At the opposite end of said shell A is the internal flange F partially cut away forming the stops H and G.

J represents the outer cylindrical shell having the usual peripheral opening K, said shell being open at one end and adapted to fit over and rotate upon the inner shell A. The opposite end of said shell J is closed at L and carries the holes M through which the screws N pass for securing the buffer 0 to the shell.

P is a plate having holes Q'therein for the passage of screws N and carrying the seg- 'mental flange R adapted to fit over the end of shell J forming the number plate for the carrier.

S is a stop or projection stamped out of the plate P and adapted to project through the slot T in the head L of shell J to engage with stops H and G to limit the relative rotation of the shells A and J to the opening or closing of apertures B and K.

U is a retaining plate mounted within the shell A and bearing against the inner side of the flange F. V is a slot in said plate U for receiving the stop S and W represents holes through which the screws N pass and are secured by the nut Y. The plate U prevents the longitudinal separation of the shells A and J and when said shells are rotated until the projection S engages the stop H as shown in Fig. 3, the openings K and B register and permit the insertion of articles into the carrier. The shells may then be reversibly rotated until the projection S engages the stop Gr (see Fig. 4:) closing the openings 13 and K and securing the articles within the carrier.

Having thus described my invention and set forth a construction embodying the same, what I claim as new and desire to secure by Letters Patent of the United States is,

1. In a carrier for pneumatic despatch tube apparatus, two cylindrical telescoping shells adapted to rotate one upon the other, each having a peripheral opening therein, a bufler secured to the outer end of each shell, means for preventing the longitudinal separation of said shells, and a fixed plate located between the outer end of one of said shells and its buffer for limiting the rotation of said shells to the cooperation or non-coe operation of said openings, said plate carrying a fixed segmental flange projecting over the end of the shell for indicating the number of the carrier.

2. In a carrier for pneumatic despatch tube apparatus, two cylindrical telescoping shells adapted to rotate one upon the other and each having a peripheral opening there- I in, a bufi'er secured to the outer end of each 5 shell, means for preventing the longitudinal separation of said shells, stops located on the inner shell, a fixed plate located between the outer end of the outer shell and its buffer andcarrying a projection adapted to engage shells, and a fixed projection on said plate for indicating the number of the carrier.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing Witnesses, this 1st day of 15 May A. D. 1908. v

ALBERT W. PEARSALL.
